go the architect of bahria town and instead of selecting from the catalouge, ask the architect to do home work first by doing site analysis which includes solar study, azimuth angles, summer solstice , after this he should be studying proper wind direction pattern. only then ull be able to get a good design layout! i am an architect myself ans\d a big shoutout for the fake and stupid architects of bahria town! they are kaam choor and in-capable! when my house was being constructed in BT, i daily visited the design wing to get the map passed. these days its a norm to make a window of size 6'x7' which is ridiculous! * even i have these in my house!
